Someone needs to make a Gamemode where you have space maps such as New Worlds, but all the buildings are small, the people are small, and the ships are small. So instead of making a bigger map just make everything in the map small. Therefore, you have tons of space to fly around in and large planets to explore and populate. You wouldn’t have to worry about your ships not being able to fit or move much. The planets would stay the same size, but they would be able to have many small buildings that small people could fit in.
I can already see that if anyone wants to use the Daedalus, Ancient Cruiser, and Wraith Hive, from the upcoming Stargate update, they will not have much space to fly and fight or even land on planets.
